I decided to edit my custom plugins using eclipse. Sequence is:
cd buildSrc
gradle eclipse
FAILURE: Could not determine which tasks to execute.
* What went wrong:
Task 'eclipse' not found in root project 'buildSrc'.
OK, so I create build.gradle and add "apply plugin: 'eclipse'
* What went wrong:
Failed to notify build listener.
Cause: Could not find any convention object of type EmbeddableJavaProject.
So then I add "apply plugin:'groovy'
* What went wrong:
Execution failed for task ':compileGroovy'.
Cause: You must assign a Groovy library to the groovy configuration!
So then I read the user manual and find you need to specify groovy
version and library, so I add this to build.gradle:
repositories {
mavenCentral()
}
dependencies {
groovy group: 'org.codehaus.groovy', name: 'groovy', version: '1.7.0'
testCompile group: 'junit', name: 'junit', version: '4.7'
}
but then I got lots of messages like:
4x4:~/dev/seis/buildSrc crotwell$ gradle eclipse

:buildSrc:compileJava
:buildSrc:compileGroovy
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

@ line 3, column 1.
import org.gradle.api.tasks.TaskAction
So, then I realize that maybe runnig gradle inside buildSrc is picking
up on the settings.gradle one directory up in my multiproject. Was
starting to get weird errors like:
* What went wrong:
Could not load compiled classes for build file
'/export/home/crotwell/dev/seis/buildSrc/build.gradle' from cache.
So, then I did "gradle -C rebuild clean" and things seemed to be ok. I
could then run "gradle -u eclipse" and it worked fine.
But then, I went to one of my regular projects and did gradle
compileJava and got this:
:buildSrc:clean
:buildSrc:compileJava UP-TO-DATE
:buildSrc:compileGroovy
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
/home/crotwell/dev/seis/buildSrc/src/main/groovy/CopyToLib.groovy: 2:
unable to resolve class org.gradle.api.DefaultTask
@ line 2, column 1.
import org.gradle.api.DefaultTask
^
So, it appears that my putting a build.gradle into my buildSrc was a
very, very bad idea!
So, some questions:
1) What do you need to put into build.gradle in buildSrc in order for
groovy files to compile like they do without a build.gradle?
2) What should a user do to allow other plugins like eclipse to be
used in buildSrc other than a build.gradle with apply plugin:
'eclipse' in buildSrc?
3) Should gradle know the difference between using a settings.gradle
in a normal project sense and when inside buildSrc?
thanks,
Philip
